[unpackme] Armadillo v6.0.0 Custom Build

July 10, 2008

Here is the latest and 'greatest' Armadillo with all the toys used to protect my unpackme.

PM or Post valid dumps, I wish to know how hard this is over v5

Working key to unlock secure sections, only use if your skills can't handle them

ArmInLine nano handler no longer works on this.

CopyMemII/Nano handler is different.

Shouldn't be too hard to do, I unpacked it so far, but can't fix nano's cause I dunno how to do them by hand.

Here is a InstantDemo of how my test app should work when properly unpacked

haven't look into the unpackme but I would say this v6 has no difference at all compared to v5...in term of difficulty of unpacking it...

yeah, stephenteh is right. Nothing is special in new version. ArmInline worked fine.

After Unpacked, just fix check key of Armadillo. (very simple, like as old version)

Hrm... ArmInLine just hangs forever here... weird.

:EDIT:

Ok, I had to kill the Parent Process first or it would hang, hehehe.

unpacked and running in trial mode... Not defeated.. If you did it correctly you would have locked sections w/ code thats missing from your dump..

Please watch the movie I posted above to see how it should work.

Hello,

do you mean the trial mode in the unpacked file?There is no trial mode anymore.

It just checks some variables.Just need to patch this routine at SUB ESP,400

to

inc eax

ret

and all is running without nag and forever.

You mean it has secured sections?

There's no way I know of to defeat that without proper key.

If you give me valid key I will unpack it fully. =]

Yes, SECURED_A & SECURED_B need to be unlocked, thats part of the challange. The msg box's are to prove the section is unlocked, not at all ment to be NAGS.... Think of them as "good job" pats

I'll also post a working key in a few days... I really wish people to own this.

Well I have tried to defeat secured sections many times without a key, and just have not found any way to do it. If someone knows a way, I and many others would love to know how to do so.

Might want to look at my first post for this unpackme, i just edited it :>

I thinks the problem like as password of winrar. When you have password for extracting files, everything is simple. If don't have it, you must bruteforce. But it's impossible with complex password.

maybe is better that others unpack because include the inyection of dll and key etc :S

hi!

i've unpacked it fully (including secured_a & secured_ with the key.

well, the protected exe doesnt work on my pc (it shows an error instead of the second "congratulations..."-messagebox and shuts down) but the deprotected one works fine.

as i trace through the copymem-routine, i figured out that the secured code is already in the coded pages.

that means the secured parts are not inserted while decoding the single pages but when the child-process is fired up (i think)

i havent worked on armadillo for a long time and to be honest: since this unpackme ive never heared of secured code at all

anyone knows where the protected code is injected or has a hint where to start searching for this part of protection?

I have analyzed it before, so I take this from another post I made elsewhere.

This is from an Arma 5.xx protected app. Basic example of the code which writes the secured sections to the process memory. The table is left incomplete unless you have a valid key.

If you get anywhere with it , please share =]

You can reach this code very easy, after breaking on VirtualProtect as normal to fix Import Redirection, scroll down and look for the call to VirtualProtect with the jmp immediately after; 003C6F2A in this example.

thanks Fungus!

i've found it in the unpackme although it's slightly different ( XOR EAX,ECX instead of XOR CL,AL and so on...)

and i agree with you - i cant see a way to beat it without a valid key since brute-forcing can take a while... or two...

but it was interesting to have a look at it.

Secured Section Table (incomplete)

It has been stated on a post on the Arteam site regarding

this unpackme from *EvOlUtIoN* that by:

Notice that in this unpackme the only necessary thing is to inject 3 environment variables:

ArmServer

ALTUSERNAME

USERKEY

If you put something in those variables before EP, all go well, even if data are not correct.

any comments?

one question for you, acidflash, on the "Armadillo not detected" nag screen. Is this only

generated if the ALTUSERNAME variable is not found?

cheers

Edited July 20, 2008 by CondZero

July 20, 2008

That is incorrect, and that tut by whynotbar is also incorrect...

As in his little video, Secured_A and Secured_B nag boxes should show up. These are contained in secured sections, which will only be written to the process memory if you enter the key he provided =]

July 20, 2008

That is incorrect

Don't blame the messenger...

Have a look below from his fixed version:

Here my unpacked

cheers

Edited July 20, 2008 by Sonny27

July 20, 2008

Hrm that is interesting indeed!

and which point do these EV's need to be injected? wonder how to do that, if so, then secured sections are defeatable without valid key, and that would be very very cool.

Correct! nice job btw! A true artist with Armidillo

	
	if (!GetEnvironmentVariable("ALTUSERNAME", name, 255)) {		MessageBox(0, "Armadillo not detected!", "ERROR!", MB_OK|MB_ICONERROR);
		return false;	};

July 21, 2008

and which point do these EV's need to be injected?

Preferably before the OEP using JMP (code cave) JMP back, although I'm sure it can be at any point

before they are referenced by GetEnvironmentVariableA ...

cheers

July 21, 2008

I don't think you can decrypt the secure section by setting ArmServer, ALTUSERNAME, USERKEY variables... My guess will be "EvOlUtIoN" register the unpackme using the key and unpacked it.
